Application filed August 5.19051 n to. 272,839. Renewed October 9. 1907. serial No. 396,659

To all whom it may concern:

Be it known that I, OTTO S RULLER,-a citizen of the United States, residing in the borough Ol'" the Bronx, city of New 1' ork', county of New York, State of New York, have in vented a certain new-and useful improvethe followingis a specification. This invention relates to. an improvement nient in'Sel'f-lgniting Gas stoves, of which simplify the meansffor igniting the gas, pare ticularly with aview to prqnlptnessol' action;

Heretofore gas-stoves have been ignited by applyin-g'a-n ignited .inatch. to the gasburners after the gas has been'tiirned on,;'-

Frequent explosions occur when-the gasstoves are ignited in this manner, and serious accidents result from these explosions;

whereas all this danger is overcome by the simplicity of construction and Operation of my device.

One of the objects of my invention is t l1erel/Vith these Objects in v1ew-,'the invention consists in certain constructionsand cornbina tic-11s as will be hereinafter 'fnllyldescribed J and. then specifically 'poin't'ed out-in tlie claims hereunto a pended. p In the drawings orrning part of this invenstoye embodied With my I improvements. Fig. 2'is a planet-same; Fig. 3 is a'detail plan of the ignitioncylinders. Fig.4 is a I with my invention.

In the several views like parts are identi, fied bylikesigns. v

.Ref'erring to' 'the 'drawings'fl, designates the body, 2- the base",. 3 the t'op'a'rid 4 the legs of a gas-stove constructed in accordance main supply pipe 5,-

is Secured tO one sid e top 3, by the ordinary. means coiri only used "by". as-fie ters, Connections 6,7,-8,9,1and 10, cocks 11,12, 13, 14,.aridr15 respectively are mounted on the supply pipe5, and are adapt-' ed to control thesupply of gas to' thesi'eed pipes 16, 17,18, 19, and 20.

Secured to the 'end of each of -the feed pipes 16, 17, 19 and. 20 are gas-burners 21, Wh1ch in gas stoves, and its principal object isto g t e gas as'the. gas.

Fig. 5 is a modified,

aving.

ends of the ignition 'cy are provided with'perfoyations '22 of a'proper size to allow sufficient gas to escape for igni- 11. J-LoscA-R scone, on

tio'n' purposes? The gas burners are so sitfeed pipe 18, and to the top 3 of the casing 1.

A cap or central portion' 25, has an internally threadedend '25 adap te d to be con, nected to the externally threaded end 24,

which holds the cap or central portion rigidly in position, Ignition cylinders 26, provided with perforations 27 are connected to the projections 28 in angular relation. The ends oi the ignition'eylinders 26are equal distance from the gas-burners 21', and point in a horizontal'plane to' the center and edge of the I -gaseburners21; Ignition pills 29 are at tached to. the inside of the ignition cylinders 26, adjacent to the channels 30formeil in-the --ce ntral portion 25.

.The ignition pills 29 are so situated thatthe platinum wires of the ignition ,pills 29 hang over the channels 36 leading into the ignition cylinders 26, so that,

the gas passing through the cha1n'1els30lead- 'ing to the ignition cylinders 26, inust'conie in contact with the, pl'atinn'm'wires of theigni tion pills 2 9, and the'gas when. mixed with the air passing through the perforations 27 in the ignition cylinders 26, causes the ignition pills 29 to become incandescent, thereby i'gniting the gas as the gas'passes through theignition cylinders 26.. A guard 31,, secured to the central portion. 25 is adapted to --pr0 tect theignition cylinders 26, and, keep the ignition pills dry.

a The operation of igniting the gasburners is asfollows: The'gas'ha'vingbeenturned.on

the s'upply pipe 5, the cook 13 is opened and the as from the supply pipe 5 passes through theeedpipe 18, to' the channel in the socket.

' 23, then up through the channels 30 in the central portion or cap 25,.to theignition cyl-1 inders 26. The gas when passing through the channels 301to' the ignition cylinders26,

comes in-contact with the air passing through I the perforations 27 in the ignition cylinders 26, andrningles freely with the air. The ac ti-on of the an and gas on the ignition pills 29,. causes the, platinum wires to become inc-an:

small flame of ignited descent, thereby ignitin the gas passing 'through' the ignition cy 'nders 26, and: a." as protrudes from the;

finders The cocks L119 11, 1 2, 14. and 1 5 can nowbe opened and the {plurality of burners,

gas'passing through the feed pipes 16, 17, 19 and 20, to the gas-burners 21 is ignited as it escapes through the perforations 22 in the gas-burners 21, by the smallflame of gas protruding from the ends of the ignition cyl1n,.

ders 26. \Vhen the gas-burners are ignited, the cook 13 is closed and the flame inthe ignition cylinders 26' is extinguished. It is obvious that all the gas-burners can be ignited at the same time, and that one or all of the gas-burners can be used at the same time- In the modified form of my 1nvent1on, as'- shown in Fig. 5, 32 designates the casing,-33'

the top of the casing and 34 the supply pipe attachedto one side of the casing. Supply cocks 35, 36 and 37 are arranged on the supply pipe 3 1 in relation to feed pipes 38, 39 and 40, which are connected to gas-burners 41 and 42 mounted on the top 33 of the casing 32. A swivel joint 43,-connected to the feed pipe 39, has a hollow connection 44 on which is mounted an ignition cylinder 45,"secured to said swivel joint 43, and is adapted to rotate the ignition cylinder 45 from burner to the other.

An ignition pill is attached to the inside of the ignition cylinder 45, adjacent to the channel in the connection 44. The ignition cylinder 45 is provided with air holes46 to facilitate the ignition of the gas passing through the ignition cylinder.

Having thus described my invention, I claim: I i v 1. A self igniting gas stove, having a burner, an "ignitio incylinder with one end adjacent to the burner, said end of the cylinder being open and the sides of the cylinder being perforated, a gas supply tube, a cap communicating therewith, a tubular channel connecting said cap with the second or remaining end of the ignition cylinder one gasand an ignition pill located within the ignicated approximately equidistant from the burners, a plurality of ignition cylinders having open-ends respectively juxtaposed to the 50 burners, the sides of the cylinders being perforated and the opposite end of the cylinders being adjacent to the gas supply pipe, means establishing communication between the said pipe and the second named ends of the cylin- -ders, an ignition pill located in each ignition cylinder adjacent to the gas supply end there, of, and a cover plate arranged over the ignition cylinders and the said gas supply 1 3. A self cated approximately equidistant from said burners, a cap secured to the discharge end ofsaid pipe, a series oftubular channels communicating with the ca ignition cylinders projected respective y toward the burners and having open ends adjacent thereto, the sides of the cylinders being perforated and an adjacent pill located at each ignition cylinder adjacent to the gas Esupplyend thereof.

4. A self igniting gas stove-comprising a plurality-of burners, a gas supply pipe lo cated approximately said burners, a cap secured to the dis- I charge end of said pipe, a series of tubular channels communicatlng with the ca ignition cylinders projected respectivey to ward the burners and having open ends adjacent thereto, the sides of the cylinders being perforated, an ignition pill located in each ignition cylinder adjacent to the gas supply end thereof, and a cover plate fastened to the said cap and protecting the ignition device and the gas connections thereto. p
